Powder bed fusion build plate thermal history indicator

Abstract

A powder bed fusion (PBF) additive manufacturing (AM) machine includes a build plate configured to function as a platform to support one or more parts built using the PBF AM machine. The build plate further includes a thermal history indicator positioned on the build plate, attached to the build plate, or physically integrated with the build plate such that the thermal history indicator experiences the same temperature as the build plate. The thermal history indicator is configured to display a durable visual indication of achievement of a temperature associated with a post-processing step performed after the one or more parts are built on the build platform.
